I've seen this problem when a client is added in the middle of the backup
cycle when incremental backups are scheduled.  For example, incremental
backups are Mon-Thu, and Full backups are on Friday, if the backup job is
added on Mon-Thu, I've seen it back up the same stuff each night.  According
to the documentation, it should recognize that it hasn't backed up this
client before, perform a full backup the first night, then incremental
backups until the next scheduled full backup.

You also might have a corrupted database and might have to clean/repair up
some stuff.  Try running nsrck -L6 and see if that fixes the problem.

Well, Dave, all good ideas, but no cigar.  This client has been part of
our backup regime for over a year -- we're on a quarterly scheme.  and I
had nsrck'ed it more than once.
Now here's the interesting part.   about 5 days after I posted this, the
phenomenom just plain stopped and went back to normal.
The owner of the machine _swears_ nothing has been changed.

Is it reporting it did a full backup (level full) or is it just backing
up 29GB for each level reported (7, 5, incr) ?


It's backing up 29gb regardless of the level.   Last night's, for
instance, was an incremental backup, and the log files say for.


If not explicitly reporting a full, there could be an archive bit issue.
Do a search on posts about the archive bit and NTFS change journal.


Thanks for the pointer.   I'll have a look.

Hi,


Our server is running Networker 7.1.1 on a Linux RH 9 system.   We
back up 58 clients -- Linux, SGI, Solaris, W2000, etc.

One of our clients, a W2000 server, had a change in its behavior
last june.   After June 26, all files on the D:\ drive started backing
up every night, regardless of whether I was runnin a level Full,
7, 5, or incremental backup.

Before that date, the backups were normal.   I haven't been able to tie
the change to any event.

Has anyone seen this happen?   If so, was there a fix?   To me, it's 29
GB of unnecessary backed up data every night.

Thanks out there.
